Phau Ntawv Qhia Txog Tricone Drill Bit Xaiv thiab siv
Nyob rau hauv rotary drilling, lubxyaum me ntsisua lub luag haujlwm tseem ceeb rau kev tawg ntawm pob zeb formations. Qhov zoo ntawm me ntsis thiab nws compatibility nrog tsim hom, pob zeb zog, thiab drilling tej yam kev mob cuam tshuam ncaj qha drilling ceev. Xaiv qhov zoo tshaj plaws me ntsis hom thiab drilling tsis raws li cov txheej txheem tsim yog qhov tseem ceeb rau kev txhim kho drilling efficiency thiab txo tus nqi. Deep-well drilling ntsib ntau yam formations thiab pob zeb hom nrog txawv zog, uaxyaum me ntsisxaiv ib txoj hauj lwm nyuaj.
- Empirical Bit Selection Method
Kuj tseem hu ua Field Drilling Data Method, qhov no yog qhov ua tau zoo thiab siv dav hauv cov kws tshaj lij. Nws tso siab rau kev txheeb xyuas cov ntaub ntawv los ntawm cov qhov dej nyob ze ntawm tib cheeb tsam, tsom rau cov hom me me uas ua tiav qhov siab tshaj plaws footage drilled thiab nruab nrab nkag mus rau hauv cov xwm txheej zoo sib xws geological thiab qhov tob. Txoj kev no yog qhov yooj yim, siv tau, thiab haum rau cov cheeb tsam uas muaj cov qauv zoo sib xws.
2. Reference-Based Method xaiv Method
Txhawm rau kov yeej cov kev txwv ntawm cov txheej txheem empirical, txoj hauv kev no suav nrog acoustic logging cov ntaub ntawv raws li qhov taw qhia tsis ncaj qha tsim, txhim kho qhov tseeb ntawm kev tshawb fawb. Paub tias yog "Txoj Kev Cai," nws xav kom cov neeg xa khoom me me los sib piv cov qauv tsim los ntawm kev txiav cov suab paj nruag nrog cov qauv kev xaiv me ntsis, ua kom cov lus pom zoo me ntsis.
3. Muaj qhov sib npaug Kev xaiv me ntsisTxoj kev
Txoj kev no ua raws li txoj hauv kev:
- Tau txais cov ntaub ntawv tsim drillability los ntawm kev sim lossis kev kwv yees.
- Siv cov ntaub ntawv txheeb cais ntawm cov ntaub ntawv khaws cov pob zeb drillability los txiav txim siab qhov nruab nrab ntawm kev xyaum xyaum (Kd) thiab tus qauv yuam kev (S) rau txhua qhov tsim.
- Nrog rau IADC tus lej xaiv daim ntawv qhia me ntsis, phim qhov tsim cov cuab yeej xyaum ua kom paub cov hom me me rau txhua qhov kev tsim geological.
4. Pom zoo Drilling Parameters rau txhua qhov tsim
Qhov kev ua tau zoo tshaj plaws ntawm axyaum me ntsistso siab rau kev xaiv qhov zoo me ntsis thiab siv qhov tsim nyog drilling tsis.
5. Drillability Profile thiab ntsis xaiv rau Puguang tsim
Siv cov ntaub ntawv geological thiab logging los ntawm qhov dej hauv cheeb tsam Puguang, qhov kev ua tau zoo me ntsis tau txheeb xyuas thiab muab faib los ntawm cov txheej txheem geological thiab qhov loj me los ntawm "Lum Ntsis Technical Efficiency Index" (JX = VL = nruab nrab mechanical penetration rate × me ntsis footage).
- Tsim thiab Lithology Profile: Paub meej cov npe txheej, tuab, thiab ntsib cov pob zeb hauv cheeb tsam Puguang.
- Drillability Profile thiab Kev Pom Zoo Me Ntsis Xaiv: Muab faib cov kev tsim los ntawm IADC cov lej raws li kev xyaum muaj peev xwm.
- Empirical Bit Selection Recommendations: Raws li cov ntaub ntawv siv hauv cheeb tsam me ntsis, qhov no muab kev pom zoo me ntsis teeb tsa rau qhov ntau thiab tsawg.
- Engineering Parameter Cov lus pom zoo: xam qhov hnyav-rau-ntsis (WOB), RPM, hydraulic zog ntsuas, thiab qhov pib WOB raws li pob zeb laum
6. Cov lus qhia rau kev xaiv qhov zoo tshaj plaws Drill Bit xaiv thiab siv
(a) Kev Xaiv Raws Li Lithology thiab Drill muaj peev xwm: Laum kev xaiv me ntsis yuav tsum tau xav txog kev tsim cov lithology thiab kev xyaum muaj peev xwm, nrog kev hloov kho raws li lithological profiles ntsib thaum lub sij hawm drilling.
(b) Cov Lus Pom Zoo rauPDC Cov: Feem ntau,PDC cov khoomyog haum rau cov mos-rau-nruab nrab formations.
- Rau cov qauv muag muag nrog cov yas siab, siv cov khoom nrog loj-inchPDCcutters thiab highcutter raug los txhim kho pob zeb-breaking efficiency.
- Rau nruab nrab-nyuaj formations nrog tsawg plasticity, xaiv cov khoom nrog me me-inch PDC cutters thiab tsis tshua muaj kev cuam tshuam los tiv thaiv cutter breakage thiab ntev lub cuab yeej.
(c) Optimizing Drilling Parameters Raws li cov qauv me me thiab cov qauv tsim: Txhim kho qhov tsis xws li WOB, RPM, thiab lub zog hydraulic-raws li cov qauv me me thiab kev tsim, thiab xyuas kom lawv nyob twj ywm nyob rau hauv qhov kev pom zoo.
(d). Txoj kev xaiv los ntawm qhov tob tob thiab cov qauv:
- Rau qhov sib sib zog nqus formations, khub PDC cov khoom nrog downhole motors rau leverage siab RPM peev xwm.
- Rau nruab nrab-qhov tob, loj-inch bore daim ntaub ntawv, nce WOB thiab txo RPM raws li qhov tsim nyog los ua kom zoo dua drilling efficiency.
